Antimatter is made up of special particles that are like opposites to the ones in regular matter, having opposite electrical charges.
In antimatter, there are antiparticles like positrons (positively charged electrons) and antiprotons. When antimatter particles meet their matching matter particles, they cancel each other out, releasing a lot of energy.
Antimatter is rare in the observable universe, but scientists find it in places with lots of energy, like cosmic rays and certain experiments in labs. People are looking into using antimatter for advanced space travel and better medical imaging.
